What does GMDSS stand for?

The correct answer is Global Maritime Distress Safety Service. GMDSS is an essential communication system used in the maritime industry that ensures vessels can send and receive distress alerts, receive safety information, and maintain communication during emergencies. It integrates various communication technologies, such as satellite and radio, to enhance safety at sea.

Understanding GMDSS is crucial for ensuring that ships can effectively communicate during distress situations, providing a rapid response to emergencies. The system involves specific protocols and equipment that are used universally in the maritime sector, contributing significantly to maritime safety and efficiency. This standardization enhances coordination among ships and rescue authorities, ultimately saving lives at sea.

The other options do not accurately reflect the purpose and components of GMDSS. They either describe non-existent or incorrect functions and systems, making option B the only accurate representation of what GMDSS stands for.
